Intentions or Aspirations of Getting Published, Advice?

So as you may notice, I have spent a considerable amount of my time researching and writing papers on psychtherapy topics. At times, I feel that my time has been wasted, as this process fails to provide me with any concrete evidence of my efforts (other than completing course requirements). In an attempt to satisify my own needs, I would like to explore the option of submitting my articles for publication in professional journals. Any advice for me?
